The Star-LedgerWilson allegedly had an open 12-ounce can of beer in the car.

HOPEWELL TWP. — The Cumberland County Sheriff’s office had the opportunity to use a recently purchased breathalyzer machine less than one hour after they installed it, although the driver had already given himself away with an open beer in the car, according to law enforcement.

The sheriff’s office received the Alcotest Machine on Dec. 5, having purchased it with money from a traffic safety grant. The sheriff said it was installed and placed into service at 12:45 p.m. Monday.
